system {dhcp server | dhcp6 server}

Configure DHCP servers used to assign IP settings, including IP addresses, to devices connected to a FortiGate interface.

History

The following table shows all newly added, changed, or removed entries as of FortiOS 6.0.

Command Description

set tftp-server <string> [<string>]

Multiple IP addresses or hostnames can now be entered, with each entry separated by a space.

config prefix-range

edit <id>

set start-prefix <prefix>

set end-prefix <prefix>

set prefix-length <length>

next

...

Configure a range for DHCPv6 server prefix delegation. Add a prefix range (starting and ending prefixes) and a prefix length, which determines the length of the prefix that the FortiGate sends downstream.
